The R2 functions are shown below.
Non-procedural data transmission/reception with external
device such as barcode reader, ID controller, general-
purpose personal computer.
Automatically updates the buffer memory between the R2
and master station at the update timing set in each area of
the R2 buffer memory.
Adds a frame registered for R2 at the head and end of the
transmission data when transmitting data.
Automatically transmits data to the external device when the
user-designated transmission conditions (changes in RX, RY,
RW and status) are established.
After transmission request is issued from the master station
to R2, forcibly cancels the transmission before R2 completes
transmission to external device.
Forcibly completes the reception when reception data from
external device has not reached the reception complete data
size, etc., and reads out the currently received data.
Stops/resumes transmission of data from external device
according to open space in R2 OS reception area.
Stops/resumes transmission of data from R2 according to
requests from external device.
Carries out ASCII-BIN conversion on the
transmitted/received data.
Assigns master station remote register (RW) and R2 side
area to be automatically updated in the buffer memory.
Clears the received data stored in the R2 OS reception area.
Registers a setting value for the R2 buffer memory's specific
application area in the EEPROM, or returns the value
registered in the EEPROM to the R2 default value.
The value for the R2 buffer memory registered in the
EEPROM (including the setting values changed by the user)
is used as an initial value at the time of the R2 startup.
Reads the status of the RS-232-C interface signal
stored in the R2 buffer memory, and controls the
output.
